Title: Added possibility to use option groups for dropdown select

Based on #114, added tests and doc.

```javascript
type: 'Select',
options: [
{
group: "Standart",
items: ["A", "AAAA", "CNAME", "MX", "SPF", "TXT"]
},
{
group: "Advanced",
items: ["NAPTR", "SRV", "PTR", "NS"]
},
{
group: "Special",
items: ["Redirect"]
}
]
```
